I used to use Astroglide, but never liked the fact that it would get kind of sticky after a while, and saliva would break it down. I now use Wet - Platinum. LOVE that stuff! It has no taste, and saliva doesn't break it down and cause it to lose its viscosity like Astroglide. Since it has nothing added to flavor it, it doesn't get sticky after a while either. It is the perfect lube for greek, and for a nice leisurely alternating HJ/BBBJ. You can get it at any CVS cheaper than Cirillas. I buy two or three bottles at time and get some awful strange looks from the ladies behind the counter
